The flame is suppose to cycle on and off. If the flame ran continously you would have a fire. And please don't use the top of it for anything such as clothes piles. Dryers need to be free of clutter on top. I know it may be hard to do but do it and your dryer will last you. Good Luck. Whatever you jumpered reverse it ok!

Just hooked up my gas dryer. worked great thru 5 loads and then quit heating,help!


What did you do move it from one place to another place? You may have shifted the lint around and cause a limit to get tripped.
Here is the manual and more

A gas dryer has a burner assembly consisting of an ignitor, 2 coils, and a flame sensor. The ignitor does 2 functions. It lights the fire and confirms the fire is on like a thermocouple. When it is heated it holds in the coil. If the glowbar is not lit then the coils will not open. The ignitor must be heated to allow that. So if the ignitor and flame sensor is fine and the dryer works when cool but stops heating when hot I would say you need to replace the solenoids.

My dryer will not heat. The pilot comes on and then it lights. The flame goes out and then it keeps recycling like this without the flame. Replaced the sensor but this is not the problem.


check your hi-limit and/or cycling thermostats as they may be going bad(bypass them with a jumper wire) or check for weak gas boost and secondary coils on the gas valve when they get weak they wont hold open the gas valve

Mdg5500aww lp gas dryer heating problem it fires once but dosent burn long clothes dont dry help


When a gas dryer starts and the burner does not stay lit more than one minute the flame sensor is not detecting the flame to as a by design safety feature the burner is automatically shut off. It is not sensing flame so it is shut off.

This is the most likely suspect. http://www.repairclinic.com/SSPartDetail.aspx?s=t-mdg5500aww-%3d%3di2681&PartID=2681

BEFORE you change this part make sure that the outside vent flapper and the ducting form the back of the dryer is free of lint. Disconnect the dryer vent and try it with nothing connected to the dryer. Also check around the lint filter area for lint especially in the bottom. If there is not a lint or ducting problem then by all means change the flame sensor.

Thanks for using FixYa!

Burner lights 5-10 seconds shuts down. Good air flow. Gas smell at times out vent.


The burner will shut off for various reasons.

First, there is a sensor right at the burner flame. If the sensor does not indicate flame the gas is shut off to avoid filling your house with gas. It is usually a short metal rod. Oftentimes cleaning it will get it working again. Or the signal from the sensor isn't getting back to the controller, so check for loose connections.

This page explains it well.
http://www.acmehowto.com/howto/appliance/dryer/gdryer/check/flamesensor.php

There are some other sensors that will shut the heat down. A temp sensor where the hot air leaves the dryer drum. This is to keep from overheating the clothes and lighting them on fire. If this sensor is bad, or the wiring to it is not getting that signal back to the controller, the dryer will shut the burner down. Although 10-15 seconds is pretty short, this is a possibility. Try different heat settings to see if you get the same result. If it only happens on one heat setting you most likely have a bad temp sensor.

Visit here for more info.
http://www.acmehowto.com/howto/appliance/dryer/gdryer/check/thermostat.php

Another possibility is that the gas valve (solenoid) is getting near the end of its life and can't stay open long. This is not likely, but still possible since the burner does light.

http://www.acmehowto.com/howto/appliance/dryer/gdryer/check/gascoil.php

Next possibility is that the gas line is partially plugged. When the burner fires the gas pressure drops rapidly. When the burner goes out the gas sneaking past the obstruction raises the pressure back up.

Final possibility is a bad controller.

Whirlpool dryer makes buzzing sound when flame should start.


Sounds like the valve is trying to open and the buzzing is the restriction of it opening. Coil is obviously correct, but actual solonoid is sticking. Replace it and see. If flame isnt detected, it will stop.

Maytag DG482 Dryer Won't Heat


The heat is regulated with a Klixon mounted next to the blower housing near the vent pipe so it can judge the temperature of the air coming out of the drum.Right next to it is a melting type fuse. If the dryer runs and gets too hot the fuse will melt.But the dryer will still run. So if the fuse is good(continuity) and the dryer control(cycle) thermostat is also good then you should have power going to the gas valve assembly when the machine is running unless the timer is in the no heat or wrinkle free/cool down mode. When the gas valve assembly is energized the flame sensor a%20flame%20sensor%202.bmp flame sensor mounted outside the burner chamber detects the heat from the ignitor. When the heat is very intense then the sensor shuts down the ignitor
a%20igniter.jpg Ignitor and that frees up the power so that the coils can be fully energised and open the gas gates. The gas comes out and hits the red hot igniter and you have ignition. It stays on for maybe 2 or 3 minutes or until the control thermostat is satisfied and shuts down power to the gas valve assembly. So... If your gas dryer has a good flame sensor and a good igniter AND the dryer will work some and quit, replace these: dryer%20coil%20kit.jpg Gas operator coils
part# 279834
The coils get hot and quit on these machines when they get a little age on them. It is aggrevating because it is a hard to diagnose thing. But well worth the 20 bucks. SOURCE

Flame shuts down after 5-8 minutes


AFTER THE BURNER SHUTS DOWN THE 1ST TIME IT SHOULD COME BACK ON WITHIN 1 TO 3 MINUTES. WHEN THE BURNER TRIES TO COME BACK ON YOU'LL HEAR A CLICK AND THE GLOW OF THE IGNITOR SHOULD BE VISIBLE. AFTER 30 TO 60 SECONDS IGNITOR SHOULD FADE AND THE BURNER SHOULD FIRE. IF IGNITOR FADES AND BURNER DOES NOT FIRE YOU WILL NEED TO REPLACE BURNER COILS #279834. IF IGNITOR DOES NOT COME ON YOU WILL HAVE A T STAT OR SENSOR ISSUE. SOUNDS LIKE COILS TO ME. HOPE THIS HELPS PLEASE FEEL FREE TO CONTAT ME HUBAPPLIANCE@COMCAST.NET. PLEASE RATE MY RESPONSE.

Gas......starts to heat then quits minutes later.


Problem is your gas solenoid coils. When they get worn they will open til they get out then shut. They will need to be replaced.

Part number 279834 replaces for most models.

Gas dryer not heating properly, burner ignites at start up, then not again


Please provide the brand and model number of your dryer.. However.. you state that your dryer is not heating properly and yet the burner ignites.. If you have a flame after ignition and your dryer is drying slowly, I would be inclined to look at the blower and or vent for restrictions in air flow. The heat generated by the burner will not be optimized in terms of drying clothes if you do not move that air out . Any and all restrictions to normal vent flow will make the dryer less efficient and dry times will be longer. If you are bound an determined to get into the flame sensor and thermostat logic, then please provide a brand and model number..
Hope this helps...

DRYER RUNS AND NO HEAT


Please tell me more as to what you have done to fix the problem.

Please check the following:

1. vent tube clear
2. lint trap/screen cleaned
3. thermostat control sensor operational
3. Flame overthrow sensor

Is your pilot light lit on your gas dryer? If it is, when turning on, does the burners fire up? If not, replace burner and control module.
